The 3D heterometallic 3d-4f coordination polymer, [EuZn(gly)(ox)(2)(H2O)(2)](n), 1, (gly = glycinate, ox = oxalate), was the product of the hydrothermal synthesis of glycinate from the reaction of tetrazole-1-acetic acid, sodium oxalate, zinc and europium salts in the presence of a trace quantity of nitric acid. Coordination polymer 1 exhibits an unusual 3D heterometallic coordination framework that is built up by heterometallic dinuclear EuZn secondary building units and mixed ox and gly linkers in a uninodal 6-connected vme {3(3).4(3).5(8).6} net. The solid-state photoluminescence and lifetime characteristics of 1 reveal intense red luminescence.
